Short for "celebration" often used in the sports world after scoring a sick goal, having a filthy dangle or in the normal world, after scoring with a hot babe. A celly is not a party; rather it is a brief expression of joy, such as a fist pump. Also used in general terms when the full word "celebration" is too lame and thus inappropriate for use.
"Dude did you see that sick celly by Gretzky after his game winner?"

"Hes havin' a fuckin giant celly right now... I bet he got some poontang earlier."
